Same age

See explanation below

Let the age of Jasmine = y

Multiplying Jasmine age by 3 and adding 6:

= (y × 3) + 6

= 3y + 6

Multiplyng the sum by 2:

2 × the sum = 2 × (3y + 6)

= 6y + 12

Let James age = z

Multiplying the age by 2 and adding 4:

James age × 2 = z × 2 = 2z

adding 4 = 2z + 4

Multiplying the sum y 3:

3 × the sum = 3 × (2z + 4)

= 6z + 12

Now since they are twins, they ae most likely same age

This means:

6y + 12 = 6z + 12

subtracting 12 from both sides:

6y = 6z

dividing both sides by 6:

y = z

Hence, Jasmine age is the same as James age

B) The expression for Jasmine = 2(3y + 6) = 6y + 12

The expression for James = 3(2z + 4) = 6z + 12

let the twin's age = 2, 3, 4, 5

when twin's age = 2

6y + 12 = 6(2) + 12 = 12 + 12 = 24

6z + 12 = 6(2) + 12 = 12 + 12 = 24

when twin's age = 3

6y + 12 = 6(3) + 12 = 18 + 12 = 30

6z + 12 = 6(3) + 12 = 18 + 12 = 30

when twin's age = 4

6y + 12 = 6(4) + 12 = 24 + 12 = 36

6z + 12 = 6(4) + 12 = 24 + 12 = 36

when twin's age = 5

6y + 12 = 6(5) + 12 = 30 + 12 = 42

6z + 12 = 6(5) + 12 = 30 + 12 = 42

Answer:

Its A

Step-by-step explanation:

that's literally what a segment is

Answer:

x = 3 and y = 5

Step-by-step explanation:

1st: The sum of the same side interior angles equal 180°. Use this to solve for x.

45x - 5 + 16x + 2 = 180

61x - 3 = 180

61x - 3 + 3 = 180 + 3

61x/61 = 183/61

x = 3

2nd: find the measure of angle 16x + 2

16x + 2

16(3) + 2

48 + 2

50°

3rd: the sum of the 50° angle and the angle 26y° is 180 since they make a straight angle. Make an equation and solve for y.

50 + 26y = 180

50 - 50 + 26y = 180 - 50

26y = 130

26y/26 =130/26

y = 5

The margin of error is 0.88.

What is a margin of error?

In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings.

Here, we have

Lower confidence interval = 21.42

Upper confidence interval = 23.18

Now,

Sample mean(x) = (Lower confidence interval + Upper confidence interval)/2

x = (21.42 + 23.18)/2

x = 44.6/2

Sample mean (x) = 22.3

Now, we find the margin of error,

margin of error = Upper confidence interval - x

= 23.18 - 22.3

A place where two or more curves, lines, or edges converge is known as a vertex in geometry (plural: vertices or vertexes), and it is frequently identified by letters like,,,. As a result of this definition, vertices are the intersection of two lines that create an angle as well as the corners of polygons and polyhedra.

The solutions are:

P' = (-4,-7)

Q ' = (-8,-7) (-8,-7)

R ' = (-3,3) (-3,3)

All you have to do is flip the provided points P, Q, and R's x and y coordinates.

The common principle is (x,y) —-> (y,x)

Thus, when we reflect across the line y = x, something like P = (-7,-4) becomes P'= (-4,-7). The similar approach is taken with the other points.

The expression that we can replace in the second equation is 4 - y, doing that, we will get the solutions:

x = -8 and y = 12

Here we have the system of equations:

x=4−y

The variable h, as the subject of the given formula is h = 3 / (G.V + 1)

From the question, we are to make h the subject in the given formula

The given equation is

(3 - h) / V = G . h

Multiply both sides of the equation by V

V × (3 - h) / V = G . h × V

3 - h = G . h . V

Add h to both sides

3 - h + h = GhV + h

3 = GhV + h

Factorize h

3 = h(G.V + 1)

Now,

Divide both sides of the equation by (G.V + 1)

The perimeter of the rectangle is 6.89

Perimeter of the rectangle:

The perimeter (P) of a rectangle is the total length of all the sides of the rectangle.

The formula for the perimeter of the rectangle is

P = 2(l + w)

The letter ‘P’ denotes the perimeter of a rectangle. Let l denote the length and w denote the width of the rectangle.

Given,

Here we have the graph with the following points:

(-3/2, -1 7/9), (7/2, -1 7/9), (7/2, 3 2/9), and (-3/2 3 2/9)

Now we need to find the perimeter of the rectangle.

To calculate the perimeter, first we have to find the length and width of the rectangle.

To calculate the length, we have to use the values of x axis,

That is,

=> -3/2 + 7/2

=> (-3+7)/2

=> 4/2

=> 2

Therefore, the length of the rectangle is 2.

Now, we have to find the width of the rectangle using the y axis coordinates,

=> -1 7/9 + 3 2/9

Convert the mixed fraction into normal form, then we get,

=> -16/9 + 29/9

=> (-16 + 29)/9

=> 13/9

Therefore, the width of the rectangle is 13/9

Now, we have to use this to calculate the perimeter of the triangle,

P = 2 (2 + 13/9)

P = 2 ((18+13)/9)

P = 2 (31/9)

P = 62/9

P = 6.89

In order to find the values of the sides of the triangle you take into account the relation between sides and hypotenuse.

h: hypotenuse

c1: shorter leg

c2: longer leg

Longer leg c2 is 3 inches longer than c1:

c2 = c1 + 3

hypotenuse h is 6 inches longer than c1:

h = c1 + 6

The formula for the calculation of the hypotenuse is:

h² = c1² + c2²

you replace for h and c2 in terms of c1:

(c1 + 6)² = c1² + (c1 + 3)²

You solve the previous equation for c1:

c1² + 12c1 + 36 = c1² + c1² + 6c1 + 9

c1² - 6c1 - 27 = 0

the roots of the previous equation are:

(c1 - 9 )(c1 + 3) = 0

c1 = 9

c1 = -3

You take the positive number because there is no length of sides with negative values.

Then, c2 and h are:

c2 = c1 + 3 = 9 + 3 = 12

h = c1 + 6 = 9 + 6 = 15

Hence, shorter leg is 9 inches, longer leg 12 inches and hypotenuse 15 inches

The standard deviation of your revenues in a day is 14.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.

Let x be the revenue from hats.

And let y be the revenue from sunglasses.

And z be the total revenue.

Then according to the question:

z = 10x + 5y

You know the expected number of hats sold in a day is 10 with standard deviation 1.

σₓ = 1

σy = 2

Taking squares of both of the equation.

σₓ² = 1² = 1

σy² = 2² = 4

To find the standard deviation of your revenues in a day:

V(z) = (10)²σₓ² + 5²σy²

V(z) = (100)(1) + (25)(4)

V(z) = 200

Standard deviation,

σz² = √(200)

σz² = 10√(2)

σz² = 14.14

σz² ≈ 14

Answer:

They are congruent by SAS:

Side: AB = CB

Angle: ∠ABD = ∠CBD

Side: BD = BD

Explanation:

Two triangles are congruent if they have the same interior angles and the same length of their corresponding sides.

If two of the angles are equal, we can say that all the interior angles are equal.

So, based on the given information we get:

1. AC ⊥ BD means that AC is perpendicular to BD, therefore,

∠ADB = ∠CDB = 90°

2. It is given that ∠A = ∠C

3. Since both of their interior angles are equal, we can say that all the interior angles are equal and:

∠ABD = ∠CBD

4. The triangle ABC is isosceles because two of their interior angles are equal, therefore AB = CB

5. BD = BD because it is the same segment.

6. By SAS (Side-angle-Side) we can say that ΔABD = ΔCBD

Because the side AB is equal to side CB, the angle ABD is equal to angle CBD, and the side BD is equal to itself.

Given p(x) = x⁴ + 4x³ - 7x² - 22x + 24 with known factors (x +4) and (x -1), you want the function written as a product of linear factors, and a sketch of the graph.

A graphing calculator can help with both parts of this. It can show you the remaining zeros are -3 and 2, so the remaining linear factors are (x +3) and (x -2). At the same time, it produces a graph of the function. This is shown in the first attachment.

Synthetic division is a convenient way to find the remaining factors of the polynomial. Dividing by (x+4) gives ...

  p(x) = (x +4)(x^3 -7x +6) . . . . . . shown in the second attachment

And dividing the cubic by (x -1) gives ...

  p(x) = (x +4)(x -1)(x^2 +x -6) . . . . . . shown in the second attachment

The quadratic will have linear terms with constants that sum to 1 and have a product of -6. These constants are 3 and -2.

The rewrite of p(x) is ...

  p(x) = (x +4)(x +3)(x -1)(x -2)

The 4th degree polynomial has a positive leading coefficient, so is above the x-axis at both the left and right ends of the graph. The graph crosses the x-axis at x = -4, -3, 1, and 2.

We note these roots are symmetrical about x=-1, so there will be a maximum at that point. That maximum is p(-1) = (-1 +4)(-1 +3)(-1 -1)(-1 -2) = 3·2·(-2)(-3) = 36. The minimum values will be found approximately halfway between -4 and -3, and again between -1 and -2. Those minima will be approximately p(-3.5) = (-.5)(.5)(-4.5)(-5.5) ≈ -6.2

The y-intercept is +24, the constant in the polynomial.

With the zero crossings, line of symmetry, local maximum, approximate local minima, and the y-intercept, we can make a passable sketch of the graph.

A graph is seen in the first attachment.
